    Former strength !

    Hi

    This is kinda of off topic but i have a question related to the aspects of a airframe.


    The plane is a 40 size Cap fairly aerobatic plane and it has some cross braces broken/missing from the formers. Each former has 2 cross braces one on the top and on the bottom, the fuse of the plane itself is sheeted. How much do u think this will hurt the integrety of the airframe for general flying purposes ?

    Iam debating if i should repair this or save weight and leave it be ?

    Any help would be appreciated


    Thanks Scott

    RE: Former strength !

    I'd replace them. The weight penalty is negligible but you can always use strength, especially on a plane of this nature. You've probably observed that most formers on planes don't have this cross bracing. If the designer went to the trouble of putting these in, they had a reason. Best to be safe than sorry, especially when the job is so quick to do.

    Just my $.02

    I concure.  1 hard landing later and the tail snaps off.  Or worse yet, an in flight structural failure.  Loose the entire model.  Repair it to spec's
    ROLL TIDE!!!
